Hi, my sister's and I are taking our mom to Italy for her 70th birthday in late April. We will have 5 days in the Tuscany Region and will probably take day tours from either Florence or Siena. We really don't want to rent a car so we thought the day tours would be a great option. Which would be a better place to stay either in Florence or Siena? Of course we want to see those cities as well. Thank you.
